Charis 144c2eadb6 fix(studio): expose notebook diff validation errors for auto-retry (#49331)
## Summary

- Automatically deny notebook tool proposals with specific error reasons
when client-side diff validation fails (e.g., unknown cell ID)
- Enables the AI Assistant to see the actual failure reason and retry
automatically instead of requiring manual user intervention
- Exposes the same `describeNotebookOperationError` helper used
server-side for consistent error messaging
- Adds `denyWithReason()` to manual tool approval handlers for flexible
denial messaging

## Test plan

- Run `pnpm --filter studio exec vitest run
apps/studio/components/ui/AIAssistantPanel/Confirm.utils.test.ts` to
verify denyWithReason tests
- Run `pnpm --filter studio exec vitest run
apps/studio/components/ui/AIAssistantPanel/NotebookProposalRenderer.test.tsx`
to verify auto-deny behavior, Skip fallback, and no re-fire after
approval is already handled
- Confirm no regressions in existing notebook tool approval flows

## Manual testing

- Get assistant to create a notebook.
- Open the notebook and manually delete a cell yourself.
- Ask the assistant to delete the cell you just deleted.
- Assistant should automatically recover from the error.

## Summary by CodeRabbit

* **New Features**
* Notebook proposals now display clear success, error, and denial
outcomes.
* Tool errors for SQL, Edge Functions, and notebooks now appear in their
respective result views.
  * Output links are supported in notebook proposal results.
* Approval panels remain visible after completed actions with
standardized status messages.

* **Bug Fixes**
* Specific denial reasons are preserved instead of showing a generic
skipped message.
* Unapplyable notebook updates are automatically denied with an
explanation.
  * Prevented duplicate denial responses after approval decisions.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
